I just tested with my script and also see a 5-8% advantage for the lower handle class.
I wouldn't call it a bug though - HTB is written for high traffic setups and trade off needs to be made between perfect behaviour and CPU usage and you say it gets better with more classes.

Well - you had 5-8% while I noticed 50-80% difference! (user1 ~76kB/s and user3 ~45kB/s).
I did notice on the graph I looked at, that it was a bit higher - I only tested with wget. I was going to repeat properly and if you were still higher suggest that you set quantums to mtu, low bursts and set
HTB_HYSTERESIS 0 in net/sched/sch_htb.c.
I also have esfq attached to classes
Of course - as you can see on the graph I created: with more classes difference beteween u1&u3 is smaller...
Hmm I only have 2+default shared by IP - but two more "above".
Can you send me the script you used for your test which gave you only 5-8%? Maybe there is something wrong with the one of mine?
OK but it won't work for you - I guess. It needs connbytes a hacked IMQ and esfq. It's just a test evolved from digriz script really.
I also have half your bandwidth - and it was set at 400kbit for the test.
Andy.
